Q: Question: When was the structure the crew of the Abana mistook for a lighthouse constructed? Passage:The Abana was sailing from Liverpool to Savannah, Georgia when she was caught in a storm in the Irish Sea. She was spotted at 3 pm drifting in a northwesterly direction with her sails torn to shreds. The crew mistook Blackpool Tower for a lighthouse and the ship was first spotted foundering at North Pier, and ended up drifting north and was wrecked off Little Bispham at 5 pm. Flares were fired and the lifeboat was called out. The alarm was raised by the landlord of the Cleveleys Hotel. Due to the weather conditions, the Blackpool lifeboat Samuel Fletcher had to be taken some overland to Bispham before it could be launched. The lifeboat had a crew of 16, and the Abana had a crew of 17, all of whom were taken on board along with the ship's dog, which belonged to Captain Danielson. The lifeboat grounded on a sandbank whilst returning to shore, but some of the crew members pushed the boat afloat and they managed to reach shore safely. All were taken to the Red Lion Inn to recover from their ordeal. The ship's bell and dog were given to the landlord of the Cleveleys Hotel, who had raised the alarm.
